Above are some manual links.

Hi, underneath if you look carefully you will see the Holes that contain the screws, no srtart in one corner, have a look at this one, there are often little arrows besides the correct ones to take out, in any event, work around the edges of the unit, undoing screws as you go.. look for all similar screws too, anyway remove them all.. now using a flat non-sharp instrument say a Butter Knife, at one corner again sort of slide the blade in between the case halves and pry open carefully. Put your screws into a container as you remove them, if there are differing types use different containers.

Observe all settings etc, write stuff down, plugs cables etc. do a drawing if necessary just go slow and methodical. Now once you have access, and that may not mean entirely taking the case in half even, whatever is required. now identify the piece you wish to replace and examine it, have a look to see how it is fastened, what wires go where etc. then remove the "Old" board, and replace it with the "new" board. (If you are confident all is well it may just pay to power up and see if it works)

If all is well, then carefully refasten it down, connect up as necessary, and make sure everything looks as it was, and close the case back up, doing the reverse procedure.. make sure you get it right first time or you'll have to do all those screws again. :)

Some screws can be under labels, so don't get caught by that one.

Always lay the unit on a big sheet of paper.
